Rio 2016: Biles to close golden Games as United States flag bearer

But after racking up four Gold medals in five attempts, Biles proved to be just as dominant in her sport. "Michael Phelps is so much taller and he seemed to carry it so easily, and I'm very short. But the gymnast, who is listed at 4'8", admits that she's a little concerned about how she'll carry the flag. And we'll add: The moment was light in part because we've all become used to expecting greatness from Biles.

On Sunday, gymnast Simone Biles will receive the honor of carrying the flag in the Closing Ceremony.

Simone Biles will conclude her golden Games by carrying the flag for the United States team at the Rio 2016 closing ceremony. "This experience has been the dream of a lifetime".

And besides all her professional accomplishments this year, the best moment of the 19-year-old's time in Rio may have been more personal - she got to meet her longtime celeb crush, Zac Efron!

In her first Olympic appearance at the Rio Games, Biles won gold medals in team, all-around, vault and floor exercise.

After the gymnastics competition ended, Biles and her Final Five teammates stayed in Rio to cheer on other athletes and hopefully visit some of Rio's famous beaches.

Biles is the first female gymnast to carry the USA flag at a closing ceremony and is just the second gymnast to carry the flag-Alfred Jochim carried the flag at the Opening Ceremony in 1936.
